Unfortunately, this place looks nicer in photos than it does in person.
First the pros: we loved the neighborhood. It's very convenient...close to several MRT/BTS stations, across from great coffee, steps from a 7/11, and near lots of street food, massages, etc. The apartment is also very spacious, and the beds are comfortable.
The cons: the place needs some love. It's very dark and rough around the edges (chipped paint, stained floors, dirty windows, etc.) Our biggest issues were that the entire downstairs smells like sewage from the downstairs bathroom and that the shower water does not get very hot. The host was available for all of our communications and tried to address our problems, but wasn't able to, so ultimately, we cut our stay short and moved elsewhere.
The outside area does not look much like the photos (more worn down), and all of the bathrooms are very dark (we actually bought a small battery operated light to be able to see better.) The place seemed as if no one had stayed in it in quite some time; it was very musty, and we had to purchase oil diffusers and spray to make it liveable. We also noticed a large cockroach in the room we were using for our two-year-old son as soon as we arrived.
Also, if you're sensitive to noise, this might not be the place for you. The unit next door (same hosts) is even larger, so there were several large groups that stayed in the two weeks we were at this listing. We could hear them partying, which wasn't a huge deal for us (it was usually short-lived), but something worth mentioning.
Again, the host was really kind and communicative, but we felt it important to list our concerns with this place so that others wouldn't be surprised. We wish we enjoyed it more, as the location is fantastic, and much better/more convenient for us than the second area we stayed in in Bangkok (Sukhumvit.)
